BIS Certification for Solar Batteries

As solar installations, electric vehicles and backup power systems grow, storage batteries have become a critical component for reliable, round-the-clock power. Because of safety risks such as overheating, leakage and fire, the Government of India has made BIS certification compulsory for notified battery categories before they can be sold.

What is BIS certification for batteries?

The Bureau of Indian Standards runs the Compulsory Registration Scheme (CRS), which regulates a notified list of electronics and energy-storage products. Under CRS, a manufacturer must have the product tested at a BIS-recognized laboratory and register it before placing it on the Indian market. The scheme ensures products meet Indian safety, quality and performance requirements and protects consumers from unsafe batteries.

Which Indian Standard applies?

Storage batteries are covered under IS 16270:2014 / IS 16270:2023, which applies to secondary cells and batteries containing alkaline or other non-acid electrolytes, including lithium-ion batteries. Key safety and performance requirements include:

• Electrical performance testing.
• Thermal safety checks.
• Protection against overcharging and short circuits.
• Mechanical strength and durability.
• Environmental resistance.

The updated IS 16270:2023 version adds requirements for modular battery technologies and energy-storage applications.

Where storage batteries are used

Rechargeable storage batteries are widely used across:

• Solar energy systems.
• Inverters and UPS systems.
• Electric vehicles.
• Telecom towers.
• Industrial machinery.

Given this broad use, confirming safety and reliability through certification is essential.

Is certification mandatory?

Yes. BIS CRS certification is compulsory for storage batteries that fall under the notified product categories. Without it, products cannot be manufactured, imported, or sold in India, businesses may face penalties and legal action, and goods can be seized by authorities. The requirement is enforced through government quality control orders covering electronics and energy-storage devices.

Who needs battery certification?

• Indian manufacturers of storage batteries.
• Foreign manufacturers exporting to India, through an Authorised Indian Representative (AIR).
• Importers and distributors.
• Brand owners and private-label companies.

The certification process, step by step

1. Identify the applicable standard (IS 16270) for your battery type.
2. Get the battery tested at a BIS-approved laboratory.
3. Prepare the documentation, including technical specifications and compliance declarations.
4. Submit the application on the BIS CRS portal with the test report.
5. BIS review and verification of the application details.
6. Grant of registration and permission to use the Standard Mark on the product.

Documents typically required

• Completed BIS application form.
• Test report from a BIS-approved laboratory.
• Manufacturing licence or business registration.
• ISO certificate of the manufacturer.
• Product technical specifications.
• Trademark certificate, where applicable.
• Authorisation letter, and AIR documents for foreign manufacturers.

Benefits of certification

• Legal compliance with Indian regulatory requirements.
• Market access to sell and distribute batteries across the country.
• Consumer trust through the BIS Standard Mark.
• Better product quality, confirmed through testing.
• Competitive advantage, as certified products are preferred over uncertified ones.
